Wireless ESP32 Smart LAN Tester

🌐 WIRELESS ESP32 SMART LAN TESTER 🌐 Are you tired of running halfway through the house for fixed network cables or pulling an endlessly long loopback cable? This enclosure set turns two ESP32-C3 Super Mini into a smart, two-part, and completely wireless network tester! Instead of a simple analog tester, these two modules communicate at lightning speed directly with each other via ESP-NOW — completely independent of a Wi-Fi router. You simply plug the remote module into the basement and read on the master module with its large 1.3" OLED display in the attic whether the line is error-free. The system not only detects cable breaks, but also shows you exactly on the display which wires have been swapped or have a short circuit. Even the shield is actively tested! ⚠️ IMPORTANT: COMPLETE DIY MANUAL INCLUDED! ⚠️ Please download the attached PDF manual from the files section! There you will find the complete DIY guide, the wiring diagram, the C++ code, and the exact Bill of Materials (BO
